French: Rolle à gorge bleue German: Blaukehlroller Spanish: Carraca Gorgiazul

Taxonomy: Eurystomus gularis Vieillot, 1819, Sierra Leone.
Has been treated as forming a superspecies with E. glaucurus, the two being very similar morphologically and behaviourally; range of E. glaucurus, however, fully encompasses that of present species, and both probably better regarded as independent species. Races intergrade in SE Nigeria and SW Cameroon. Two subspecies recognized.

Subspecies and Distribution:

  • gularis Vieillot, 1819 - Guinea to SE Nigeria and SW Cameroon.
  • neglectus Neumann, 1908 - SE Nigeria and S Cameroon E to C Uganda, and S to NW Angola.
